The quality of water in Japan has improved considerably. However, in closed waters such as inland seas, inner bays, and lakes, and in small and medium-sized rivers in cities, these water quality improvements are still inconvenient.
For this reason, with regard to wastewater from factories and business establishments, wastewater regulations based on the law (Water Pollution Control Law) have been implemented, and certain results have been achieved. However, there are many small businesses that are not subject to legal regulations. Small restaurants and food treatment plants are equivalent to this.
In order to further improve water quality, voluntary efforts are expected, such as by introducing low-cost, compact, and easy-to-maintain wastewater treatment technology that can be introduced even in small-scale business establishments.
The ETV program believes that it will be useful for selecting technologies that meet the needs of users by disclosing the results of third-party technology Verification tests and providing various information necessary to determine the effectiveness of the technology.
[Reference] What is drainage regulation?
Based on the Water Pollution Control Law, national standards are set for water discharged from factories and business establishments where facilities that discharge sewage into public water bodies (specified by government ordinance as “specific facilities”) are established. It is. However, in water areas where pollution sources are concentrated, it may be difficult to achieve environmental standards based on uniform standards established by the government. For such waters, prefectures are able to set standards (additional standards) that are stricter than the uniform standards. When an extra standard is established, the regulations of the Water Pollution Control Law are applied according to the standard value. Additional standards are set according to the actual conditions of the region in all prefectures.
In the survey on ETV targeting local governments nationwide, although there is a need for technology, the spread of technology has not been achieved. One of the reasons is that the effectiveness of the technology is difficult to understand, and that something that is cheap is required.
The ETV program provides users with an overview of environmental technologies that can be used, publishes the results of technology Verification tests by third parties, and provides various information necessary for the user's technology selection. We believe that it will help potential users to expand the spread of useful technologies for verification applicants.
In fact, in the questionnaire survey targeting past applicants for the verification, the response was “Inquiry about technology increased after the verification”, “There was some effect on activities such as sales promotion and technology development,” In addition, regarding the issued ETV logo mark, there is a reply that it is “published in product brochures, technical reports, external booklets, company websites, etc.”.
